IMPROVEMENT IN HORSE-POWERS. I

The Schedule referred to in these Letters Patent and making part of thesame.

I, DANIEL G. MARDEN, of Memphis, in the county of Shelby, Tennessee,bave invented an Improved Horse-Power, of which the following is aspecication.

.Nat-ure and Objects of the Invention.

The subject-matter of my invention is a spur-wheel horse-power adaptedto work either on the ground or overhead, tbe horse or horses workingover or under it, and in either an upright or an inverted position, asmay be most convenient.

The improvements consist- First, in cup-boxes of peculiarconstruction,.to support both ends of each secondary vertical shaft.

Second, in a coupling-box for a shaft, for the at tachment of the sweepwhen the power is overhead,

by means of which said shaft may be removed without disturbing the powerDescription of the Accompanying Drawing.

Figure l is a plan View of my improved horse-power as arranged on theground, the sweep being oft', and its position indicated by dottedlines, and a portion of the framing broken away lto expose internalparts.

Figure 2 is a central longitudinal section of the same.

Figure 3 is a side elevation of the apparatus as arranged on an elevatedor upper door, and adaptedfor the horses to work under it by aninversion of its driving-shaft only.

Figure 4 is a side .elevation of the apparatus as Working in an invertedposition.

Like letters of reference indicate corresponding par-tsn the severalfigures.

General Description.A

My improved horse-power has a frame composed of two horizontal plates, AB, which may be'cast from a common pattern, .and` four (more or less)pillars, C, which may also be unlform.

The said pillars are constructed with shoulders c and screw-stems c atboth ends, the latter passing through perforations in the plates, andprovided with nuts D, by which the plates are clamped down on the saidshoulders.4 They thus serve to support the plates A motion, and thelatter with the last secondary vertical shaft, F2, by a pair ofbevel-gears, I J.

The motion is taken from a pulley, K, (or its equivalent,) on the lastor parallel shaft G and imparted to the main or driving-shaft E througha sweep, L, to which the animal or animals are hitched in any manner.

For the attachment of the sweep L the said driving-shaft Eis providedwith a perforation or seat, e, for a transverse key, M, or anyequivalent coupling.A

The driving-shaft E is stepped at one end in a cupbox, N. Its other endprojects through the opposite plate A, and is journaled in a box orsleeve, 0, attached thereto by set-screws, and held by a removablecollar, P, attached by a set-screw, 11, or its equivalent.

Thesecondary vertical shafts F F F2 are each stepped at both ends incup-boxes N.

The horizontal or parallel shaft G is supported at its inner end by two(or one or morelbearings, Q, and, if necessary, at its outer end, and atintermediate points, byadditional bearings, R, of any approved yconstruction.

The several gears are keyed or otherwise attached to or cast on theshafts.

The cup-boxes N are constructed with shoulders 'n and screW-stems'n, andattached to the plates A B by nuts S applied to said stems. They arethus firmly attached, and may be'readily removed.

The bearings Q may consist of brackets q and caps' q', and may beattached to one or both of the plates A B by set-screws. They may belubricated by any sufficient means.

It will be seen that the driving-shaft E, on its uuder collar O and gearH, being loosened, may be removed, and, with its bearings, reversed fromtb'e position represented in figs. 1 and, 2 without disturbing theremainder of the apparatus. The apparatus thus adj usted is shown iniig. 3. This may be convenient in some cases, where as much space as canbe obtained is at some times needed on the ground, and at otbers'cn thetloor above. n

The preferred adjustment of tbe apparatus for working overhead is shownin g. 4. The same is here represented as simply inverted. The cup-boxbearings N, for the several secondary vertical shafts F F1 F2,

adapt the same to workin this position equally as well equivalent) ofthesame.

When thepower is to be overhead a vertical shaft, U, is required for theattachment of the sweep.

The lower end of this shaft hasthe usual metal tip.-

`or trunnicu V, and is stepped in a cup-box, W, the upper surface ofwhich may be Hush with the ground or-loor.v Its upper end I provide witha couplingbox, X, having a key-seat, x, (or its equivalent,)corresponding with 'l, and constructed, further, with a removable side,m1, which may be secured by bolts Y Ulalms.

I claim as my invention- 1. The cup-boxes N, constructedwith shoulders nand with screw-Shanks n', for the reception of nuts S, as described andshown, for the purposes set forth.

2. The improved spur-wheel horse -power herein described, having bothends of each secondary vertical shaft stepped in cup-boxes N and lthusrendered reversiblefas set forth.

U, constructed with a removable side, az', as and for the purpose setforth.
